Abstract:This study utilizes CT scan data of canine thoracic and abdominal regions,employing 3D Slicer software for data rendering and 3D reconstruction,followed by anatomical segmentation and refinement of the generated models.Ultimately,models of the main organs in the canine thoracic and abdominal cavities were constructed,including parenchymal organs such as the liver,spleen,and kidneys,as well as hollow organs such as the heart,lungs,stomach,small intestine,large intestine,and bladder.Subsequently,an AR 3D anatomy software was developed using Unity3D,enabling the 3D visualization of the anatomical structures of the main organs in the canine thoracic and abdominal cavities.The aim was to assist in the diagnosis of canine diseases.The results indicate that 3D Slicer can successfully construct models of some canine abdominal organs,providing a reference for the diagnosis of clinical canine abdominal organ diseases.This study also enhances students' understanding of relevant anatomical forms and structures,offering valuable resources for educational purposes.
